The nackCount property of the
RTCRtpStreamStats dictionary is a numeric value indicating the number
of times the receiver sent a NACK packet to the sender. A NACK
(Negative ACKnowledgement, also called "Generic NACK") packet tells the sender that one
or more of the RTP packets it sent were lost in transport.
Syntax
var nackCount = RTCRtpStreamStats.nackCount;Value
An integer value indicating how many times the receiver sent a NACK packet to the sender after detecting that one or more packets were lost during transport.
Note: This value is only available on the receiver.
